I can't think that would happen Todd. The IdaSailor rudders are exceptionally stout, and if it's the cheek plate to blade joinery that you'd suspect, it's very similar to the M15 setup, and I've never experienced that phenomenon in that boat. But heck, maybe. Perhaps Larry or Randy can add some thoughts... I too have seen the result of a hard stop on the stationary rudder close up. It's a real ugly sight. t /)) Tom Smith & Jane VanWinkle M15/345--Chukar M17/496--Unnamed
